GPU-Z won't show hot spot temperature for RTX 5090.

NVIDIA has decided to disable the sensor entirely.

Performance aside, there are other interesting topics arising from today's review coverage of RTX 5090 cards. NVIDIA has spoken a lot about its new dual-slot cooler design, which is intended to handle higher power requirements. However, there is a change that has not yet been mentioned.

According to Wizzard, TechPowerUP's tech reviewer and the creator of the GPU-Z tool, NVIDIA has removed the Hot Spot sensor from RTX 5090 cards. Other reviewers have also noted that the current data produced by this sensor shows 255°C, which is obviously incorrect.

With Blackwell, NVIDIA has removed the "Hot Spot" sensor, you still have access to "GPU Temperature" and "Memory Temperature".

While there was always some drama around Hot Spot, it was useful to diagnose a misaligned cooler or waterblock.

Reviewers who want to test the latest version of GPU-Z can contact Wizzard for the newest beta, which should no longer display this sensor data. A stable release of GPU-Z is presumably planned for next week, aligning with the launch of the RTX 5080 cards.

The Hot Spot is not a single sensor but rather a method of reporting the highest temperature across the GPU die and multiple sensors. This feature might return in some form in the future, but as of now, there is no way to access such data through the NVIDIA API.
